-2011- Computer History

Today’s world is invaded by the product of a relatively new,very

dynamic,with major implications in all areas of humanactivity,including at home.It is the science and computerengineering,which concern,in a hitherto unknown extent or anotherarea,both specialists and field results on users.The worl wants toknow more about computer system,their capabilities are,what can beused and what not.All who know the buton at least once acomputer,for example games,more or less fun,easy to learn,sohandy.However,very few know the information about the appearanceof computers in the world. Thus,more than 300 years ago,namely in 1642,inventing the firstmachine arithmetic Blaise Pascal(1623-1662),mathematician,physicist,writweer and philosopher Frenchrealized that this mechanism representing a tool of thought,is and willremain a creative technique.In this sense,his meditations hesaid:”Machine arithmetic effect is closer to thought than all theanimals are,but not anyting we could say that it has determined itwill,like animals”.By definition,means a computer is any computingsystem.which allows it to be arithmetic or algebraic operationsperformed according to a predetermined schedule. America in 1885,William Seward Burroughs(1857-1898)moveto the manufacture of a souped-up car computing.Since 1920 a newphase in building computer machines,now passing in front on theintroduction of electromagnetic device such as alectromagneticrelays,electrical sensors,electric motor and printing informations onpaper tape or punched cards. Between 1939-1944 professor H. Aiken of HarvardUniversity,together with specialists for the International BuisnessMachine (IBM) has developed the first automatic computer,calledMark-1.It was an electromechanical computer in the scheme whichwhere mainly used electromagnetic relays.Meanwhile,JohnNewmann to developed the computer coding operations by applyingthe bynari code.In a short perios after the realization of Mark-1computer,it comes to making computers with vacuum tubes,alsocalled I.The first generation computer of this generation computerscalled ENIAC,was conducted between 1942-1946 at the University ofPennsilvanya.The computer contained about 18000 vacuumtubes,was quite bulky and its operation requires a relatively highconsumer power.In our country the first electronic computer wasdeveloped by IFA in 1957.He was a computer with vacuum tubes,so Ialso have a generation rate of 50 operations per second.This computerI was given the name of CIFA-1.Other computers were alsoconducted at the Polytehnic Institute in Timisoara and Clujcomputing.Today almost no areas that have not entered the electroniccomputer.Daily newspapers and magazines bring us news about thevarious applications of computers.
